HEATlNG-DRUM.

SPECIFICATION forming part of Letters Patent No. 711,969, dated October 28, 1902. Application filed April 23,1901. Serial No. 57,044. (No model.)

T0 all whom it m/ay con/06777,:

Be it known that I, EDWARD HINDERER, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, (whose post-office address is 195 W'est Sixth street,) have invented certain new and useful Improvements in Heating-Dru ms, of which the following is a specification.

My invention relates to improvements in heating-drums for stoves, its object being to provide a heating-drum constructed of ordinary stovepipe and adjustable in size, said drum being so constructed that it may be supported by the Outlet-pipe of Ithe stove and also being adapted to be arranged in connection With the pipe in an adjacent room and rest upon the floor. I further provide my improved drum with a novel arran gement of airconducting conduits.

In the accompanying drawings, forming part of the specification, Figure 1 is a front elevation of my improved drum,partly broken away. Fig. 2 is a side elevation, and Fig. 3 is a top plan of Fig. 1.

In the drawings, Arepresents a stovepipesection enlarged at its lower end to fit over the flange of the stove-opening and serving as a support for the drum. The pipe A passes through the chamber 2 at the bottom of the drum, leaving a passage between itself and the walls of the chamber. Extending outwardly from the opposite sides of the chamber 2 are the pipes 3, connected With the vertical pipes 4 by elbows 5. The upper ends of the Vertical pipes 4 are similarly connected With pipes 6, opening into the sides of the chamber 7, by means of elbows 8. The bottom of the chamber 7, as shown in Fig. 1, is connected with the pipe A by the pipe-section 9, and the top of the chamber 7 is connected by a pipe 10 with the chimney. Within the chamber 7 is pivoted the damper 11, which Works in connection with the diagonal partition 12. When the damper is closed, it will be evident from Fig. 1 that the smoke and products of combustion will be deflected from the pipe to'the right-hand side of the drum, passing through the right-hand pipe 4, through the chamber 2, up through the lefthand pipe 4, and through the left-hand side of the chamber 7 and pipe 10 to the chimney.

Extending centrally through each of the pipes 4 is the air-pipe 13. These pipes are connected With the lower elbows of the drum' by the brackets and bolts 14 and 15 and similarly connected with the upper elbows of the drum by brackets and bolts 16 and 17. The lower ends of. the air-pipes 13 preferably extend nearly to the floor and at their upper ends are preferably joined by the elbows 18 to a central pipe 19, by which the heated air may be conducted to a separate room.

In adjusting the size of the drum the pipesection 9 and the 'vertical pipes 4 are adapted to be removed and shorter or longer Sections substituted. The airpipes are then again secured to the elbows of the drum to hold the parts together in their proper relations.

I claim- 1. A heating-drum of the class described, comprising in combination a central pipe, a chamber inclosing the lower end of said pipe, a chamber connected with the upper end of said pipe, branch pipes extending outwardly from the opposite sides of said chambers, vertical pipes connecting said branch pipes, and air-pipes extending through each of said vertical pipes and connected above the rear of said upper chamber.

' 2. A heating-drum of the class described, consisting of an upper and lower chamber, a

central pipe connected With the bottom of the upper chamber, and an Outlet-pipe connected with the opposite side of said upper chamber, outwardly-projecting pipes connected With the opposite sides of said chambers, Vertical pipes removably connected with said outwardly-projeoting chamber-pipes, air-pipes extending through said Vertical pipes, and means for detachably connecting said airpipes to the inclosing pipes as and for the purpose set forth.

3. A heating-drum of the class described, the combination of upper and lower chambers, a central pipe secured in said lower chamber, a central pipe connected with the bottom of said upper chamber, an oppositelyarranged Outlet-pipe, a damper in said upper Chamber, laterally-extending pipes having In testimony Whereof I affix my signature adjustabie connection With the sides of said in presence of two Witnesses.

ehambers Vertical pipes removably connecting said lteral pipes, and air-pipes extend- EDWARD HINDERER` 5 ing through said Vertical pipes and remov- Witnesses:

ably secured thereto, as and for the purpose H. S. JOHNSON,

set forth. EMILY EASTMAN.
